The validation and evaluation of the prognostic model. a, c, e Decision curve analyses of the model predicting cancer specific survival (CSS) at 12-Mo, 36-Mo and 60-Mo. X-axis shows different thresholds. Y-axis represents the net benefit. Net benefit was counted as summing the true positives and subtracting the false positives. The black horizontal line assumes that no patients died whereas the green line assumes all cases dead. b, d, f Calibration curves of CSS at different timepoints (12-, 36- and 60-Mo)
